jcb857 161 #1 Posted February 8, 2011 I have been looking for a hole plug for my 401 and I was told a knock out plug for a breaker box would work so I went to United Electric and looked around the store and told the sales person what I was looking for and the only thing he had was a two piece plug and it was $25 so I passed on it. The only other thing I could find that might work is a plug that looks like a plug that comes on a new oil tank but without the threads. Does anyone have a pic of what the originals looked like and does anyone have a pic of a replacement one and can they tell me where they bought it at.
